Nothing says Hammer Films like repressed Christians, the Victorian age, and whole lot of pent up sexual frustrations. Enter: Demons of the Mind from 1972.
In this film, true to Hammer Films form, and according to Wikipedia “…a widower locks up his two children, afraid that they will go mad, as did his wife. He then invites a doctor of dubious reputation to supervise the young people’s mental health. Meanwhile, in the vicinity of the house, grisly murders are happening.”
Coincidence? Madness? Actual demons? Well to find out answers to those questions you’ll need to find yourself a copy of this bad boy. In the mean time just bask in the glory of this beautifully illustrated horror poster. They just don’t make them like this any more.
